説明
Two selectable differential input channels for flexible sensor connections
On-Chip active low-noise programmable gain amplifier (PGA) with selectable gains of 3264 and 128 for wide dynamic range and precise signal amplification before conversion
On-Chip power supply regulator for load cells (strain gauges) and the analog ADC supply, delivering stable, clean power and reducing need for external regulation
On-Chip oscillator that requires no external components, with optional external crystal for timing precision, plus On-Chip Power-On Reset for reliable startup
Key benefits and what it solves
- Integrated solution: All essential analog front-end functions are on a single chip, reducing system complexity and external component count
- Flexible sensing: Two differential input channels enable simultaneous measurement from two sensors or differential pairing within a single sensor
- High dynamic range: Adjustable PGA gains provide strong amplification for low-level signals while preserving accuracy for higher signals
- Stable power for precision measurements: On-chip regulators supply the load cell and ADC, improving measurement stability and reducing noise from external power sources
- Simple timing options: An internal oscillator with optional external crystal simplifies clocking while allowing high-precision timing when needed
- Safe startup behavior: On-Chip Power-On Reset ensures predictable, reliable initialization of the measurement system
Typical applications and use scenarios
- Industrial weighing and force measurement: Connect load cells to two differential inputs, use the adjustable PGA to optimize signal levels for precise weight or force readings in automation and process control environments
- Precision data acquisition systems: Integrate into measurement modules where clean analog supply and differential sensing are critical, enabling high-resolution data capture with minimal external circuitry
- Embedded instrumentation and test benches: Build compact, low-component-count measurement solutions that require no external oscillator components, yet can accept an external crystal if tighter timing is required
Notes
- The device provides two selectable differential input channels for versatile sensor interfacing
- The PGA offers selectable gain values of 3264 and 128 to cover a wide input range while maintaining signal integrity
- The on-chip regulator supports both load cell excitation and the analog ADC supply
- The onboard oscillator supports no-external-component operation, with option to use an external crystal, and includes a Power-On Reset for deterministic startup
This description preserves the original function and capabilities while presenting clear, customer-focused benefits and practical use cases.
